Dr. Chalifoux specializes in failure analysis of structures and components by utilizing her multidisciplinary expertise in corrosion, coatings, fracture mechanics, and materials science. Dr. Chalifoux is NACE CIP Level 2 certified and conducts analyses of various paint and protective-coating systems applied to a wide variety of substrates including steel, aluminum, wood and cementitious structures. Her experience in coating failure analysis includes evaluation and root cause analysis of failure mechanisms involving delamination, cracking, blistering, peeling, and chalking.
Dr. Chalifoux also has experience analyzing corrosion and fracture of ferrous and non-ferrous metals including intergranular corrosion, pitting corrosion, filiform corrosion, corrosion fatigue, stress corrosion cracking, hydrogen embrittlement, hydrogen environmental assisted cracking, and liquid metal embrittlement. Dr. Chalifoux's metallurgical analysis capabilities include mechanical testing, fractography, optical and electron microscopy.
Prior to joining Exponent, Dr. Chalifoux was a graduate research assistant at the University of Virginia, where her research focused on experimental fracture mechanics of Al-Mg alloys. She designed and implemented electrochemical crack tip controlled experiments and hydrogen charging experiments to validate the hypothesized coupled dissolution-hydrogen embrittlement mechanism for intergranular stress corrosion cracking in Al-Mg alloys. Dr. Chalifoux developed her microscopy skill set using a scanning electron microscope (SEM) to analyze and document fracture patterns generated during corrosion fatigue, stress corrosion cracking, and hydrogen embrittlement of Al-Mg alloys in various electrochemical environments. In addition, Dr. Chalifoux studied high temperature fatigue in nickel-based super alloys.
